Abstract

The invention relates to an arrangement of a pressure limiting valve (1) for the pilot control of the pressure control valve of a hydraulically actuatable shifting element of a transmission of a motor vehicle, wherein the pressure limiting valve (1) is disposed such that the armature axis thereof is disposed perpendicular to the driving direction, or to the longitudinal axis of the vehicle.
